Abstract
First molecular studies on museum specimens of five families of pentatomoid bugs, namely Cydnidae, Dinidoridae, Par-astrachiidae, Tessaratomidae, and Thyreocoridae (Hemiptera: Heteroptera: Pentatomoidea), are presented, as a preliminary approach to molecular phylogenetic analyses of these families. Forty-eight pin-mounted museum specimens representing 46 pentatomoid species collected in the late 19lh and the 20th century (more than 15 years old, the oldest specimen collected in 1894) were analyzed; and the acquisition of PCR amplifiable mitochondrial DNA (16S and/or 12S rDNA fragments) was successful from 10 specimens, i.e., 2 specimens (2 species) of Cydnidae, 4 specimens (4 species) of Dinidoridae, 1 specimen (1 species) of Parastrachiidae, 1 specimen (1 species) of Tessaratomidae, and 2 specimens (2 species) of Thyreocoridae. The oldest PCR amplifiable mtDNA sample was extracted from Strombosoma impictum (Stal) (Thyreocoridae) collected in 1932 in Zaire.
